Outside Processing Acceptance Form for Tooling: Template, Criteria & Receiving Control

Outside processing tooling form preview with receiving control and QC sections
Technical overview of the 5-section tooling form: routing control, part-level subcontract records, incoming QC checks, NCR/rework tracking, and final engineering release.

Use this page to control outside processing for tooling components before parts leave your shop and before they are released back into mold assembly. It applies to heat treatment, plating, texturing, grinding, EDM recovery, and other controlled subcontract operations. It gives purchasing teams, SQEs, and tooling engineers one clear control rule: a part should not be released out without defined requirements, and it should not be released back in without verified records and inspection closure. Required returned evidence typically includes part number and revision confirmation, process certificates or logs, CTQ verification results, and disposition records before receiving can release the lot. Use this tool seamlessly within your broader validation and quality control for injection mold programs structure.

Deploy this quality framework alongside our established injection molding checklists and quality templates when your tooling program requires stringent returned records, receiving verification, and release control at the factory gate.

What Is an Outside Processing Acceptance Form?

An outside processing acceptance form is a controlled document used to release parts to an external processor and verify them on return. It links the part number, drawing revision and mold layout control, outsourced operation, CTQ-based mold validation evidence, acceptance criteria, required returned records, and final disposition before the lot can be released to the next tooling or assembly step. Depending on the process, returned evidence may include hardness data, coating thickness verification, texture reference confirmation, dimensional recheck results, or approved deviation records.

For precision tooling suppliers, outside processing must be controlled not only by process instruction, but also by revision alignment, returned records, and receiving verification. This form creates a defined release-and-return gate to catch wrong revision processing, missing records, dimensional movement, hardness drift, or undocumented rework before the part moves to assembly or trial. Typical control items include part number and revision match, outsourced process confirmation, CTQ dimensions or surface requirements, required returned records, and receiving disposition before assembly release.

Document Type Primary Purpose Document Owner What It Does Not Control
Purchase Order (PO) Authorizes commercial terms, job costs, quantities, and delivery schedules for the external vendor. Procurement / Purchasing Technical processing parameters, mid-process engineering revisions, or specific inspection methods.
Routing Sheet Tracks the sequence of internal manufacturing steps and physical location transitions across the factory floor. Production Control / Ops Detailed supplier quality requirements, dimensional hold/release logic, or raw verification data logs.
Outside Processing Acceptance Form Enforces process-specific technical limits, drawing revision alignment, required supplier return documents, CTQ verification, and receiving release criteria. Quality Engineering / SQE Commercial billing structures, outbound shipping logistics, or macro-level production scheduling.
Receiving Record Logs the physical receipt, package counts, and logistical arrival status of an incoming shipment at the dock. Warehouse / Inventory Critical-to-Quality (CTQ) tolerances, supplier-returned technical evidence, precise hardness ranges, or downstream assembly approval.

When Should You Use an Outside Processing Acceptance Form for Tooling Components?

Generic routing sheets do not control revision alignment, required returned records, or receiving verification after outside vendor processing. Use this form when outsourced processing can change hardness, dimensions, surface condition, or assembly fit and the part cannot return to tooling assembly without defined verification.

When NOT to Use This Form: Scope Limitations & Quality Boundaries

This outside processing acceptance form should not be treated as a complete quality management system or a substitute for program-level validation and compliance controls. This form is limited to outside processing release, supplier-returned records, and receiving verification before the part moves to the next tooling step.

Does Not Replace PFMEA

This form verifies revision match, required returned records, and defined CTQ checks when the part returns; it does not identify process failure modes, assign RPN values, or establish preventive controls for the subcontractor’s process.

Does Not Substitute for PPAP

For automotive or volume production programs, this form cannot replace formal PPAP requirements. Complete control plans, gauge R&R, and process capability studies must still follow standard PPAP document requirements for production programs.

Does Not Replace IQC Procedures

While this form directs receiving personnel on outsourced operation checks, it does not replace your facility’s Incoming Quality Control (IQC) procedures, quarantine process, or sampling plan (AQL). Use this form alongside IQC procedures when the lot returns from outside processing; do not use it as a replacement for quarantine, sampling, or incoming release rules.

Not a Full Validation Alternative

This form should supplement, not replace, your program-level quality documents, FAI records, and approval deliverables. Safety-critical or high-complexity tooling may still require FAI records, capability evidence, change approval, and program-level validation documents beyond this form. Refer to standard quality documents and FAI deliverables.

No Independent Regulatory Clearance

This form does not provide standalone compliance for regulated medical, aerospace, or defense programs that require AS9100 FAI, ISO 13485 traceability controls, or separate environmental compliance declarations. This form can support traceability, but it cannot be used as a standalone compliance record for regulated medical, aerospace, defense, or environmental approval requirements.

What Must Be Defined Before Parts Are Released to an Outside Supplier

Outside processing form fields showing revision control CTQ and sign-off blocks
Figure 3.1: Form-field view showing revision control, CTQ requirements, mandatory return records, and release/sign-off blocks before outside processing.

Sending tooling components to an outside supplier without documented release requirements is a common cause of rework. Before any core insert, cavity block, slider, lifter, or wear component is released, the form should define the part number, drawing revision, outsourced process, CTQ limits, required returned records, and sign-off owner. At minimum, the release record should define the part number, drawing revision, outsourced process, CTQ features, acceptance limits, required return documents, and sign-off owner before the part is shipped.

Part Identity and Revision Control

Every component sent to an outside vendor must be tied to the current part number, drawing revision, and job or lot identification. The buyer or tooling team should match the physical part to the active drawing, revision record, and release form so engineering changes do not get lost between drawing update and shop-floor execution. Part identification should include part number, revision, job or lot number, and any active ECN status that affects outsourced processing, matching active setups with standard revision control for mold drawings and outsourced operations.

Outsourced Process and Technical Requirement

If the process requirement is vague, the supplier may default to its standard shop process instead of the tooling-specific requirement. Outbound documentation must define variables such as nitriding depth, plating type, coating thickness, surface finish requirement, and masking instructions for functional fits or bores. The release form should define the exact process type, key technical requirement, masking boundary, and inspection reference so the supplier does not default to a shop-standard process.

CTQ Features and Acceptance Criteria

Isolating critical-to-quality elements focuses the sub-vendor's validation efforts directly on features that govern ultimate tool performance. Defining CTQ dimensions and acceptance limits before release prevents dimensional movement, coating buildup, or heat-treatment distortion from going unreported after processing, establishing objective lines for what tolerances can actually be verified after processing.

Required Returned Documents

Metallurgical and dimensional condition cannot be confirmed by visual receiving inspection alone. The release form should require the supplier to return the specified records, such as furnace logs, hardness reports, thickness reports, CMM reports, and lot traceability documents, before the lot can be closed. Returned records should match the outsourced process, such as furnace logs for heat treatment, thickness reports for plating, gloss or reference approval for texturing, and CMM reports for dimensional recovery work.

Sign-Off Responsibilities

If release and return ownership is unclear, unverified parts can bypass receiving inspection and move into final tool assembly. Clear release and return sign-off rules create a traceable checklist for shipment release, receiving verification, and final disposition, grounding operational compliance onto the master inspection checklist for receiving and release sign-off.

Outbound Risk Control Matrix

Form Field Group Why It Matters (Engineering Purpose) Risk Factor If Missing Verification Owner
Identification & Revision Confirms the part matches the active drawing and revision level. Supplier processes the wrong revision or outdated geometry, causing tool assembly mismatch. Tooling Engineer / Buyer
Technical Requirements Enforces strict operating setups like local hardening windows or bore masking. Subcontractor defaults to common shop process, reducing surface hardness or layer adhesion. Manufacturing Engineer
CTQ & Acceptance Limits Identifies precision fitting dimensions and key sealing alignment datums. Uncontrolled coating thickness or material warpage yields insert binding or early tool flash. Quality Engineer / SQE
Mandatory Return Docs Secures objective evidence of batch processing via direct technical charts. Total loss of validation history; structural and internal finish defects remain unchecked. Incoming QC Inspector
Sign-Off & Responsibility Locks structural authorization gates for outbound transport and incoming sign-off. Unchecked components mix directly into active assemblies, multiplying unrecorded tool-room errors. Quality Manager

Acceptance Criteria by Outside Process

Acceptance matrix for outside processing with CTQ checks and hold triggers
Technical definition matrix mapping process limits, dimensional criteria, and mandatory supplier return records evaluated at incoming inspection.

US engineering and procurement teams often see variation in outsourced tooling work, especially when returned parts are released without a defined acceptance matrix. This matrix defines the required CTQ checks, verification methods, acceptance limits, returned records, and hold triggers before any outsourced part is released to the next tooling step.

By matching technical callouts directly with quantitative shop-floor inspection requirements, sourcing teams can maintain strict configuration tracing across highly specialized secondary vendor environments. This layout guarantees that structural parts remain within predictable operational ranges before dynamic tool integration.

Operation Typical Tooling Parts CTQ to Verify Method Acceptance Limit Returned Record Hold Trigger
Heat Treatment Core inserts, cavity blocks, slider components, lifter heads (H13, S136) Metallurgical Hardness, dimensional movement, and visible cracking or surface damage after heat treatment Rockwell hardness testing at defined locations; dimensional recheck by CMM or fixture measurement against the drawing or inspection datum 48–52 HRC where specified, or per drawing requirement; dimensional movement within drawing or grinding allowance; no visible cracking or heat-treatment damage under specified inspection Furnace record, hardness report, and lot traceability record Hardness variance exceeding limits from print specification; dimensional movement exceeding final grinding stock allowances; missing or illegible furnace logs
Plating / Coating Ejector pins, guide bushings, wear plates, core pins, mechanical linkage cams Surface Finish Coating thickness, adhesion, and protection of masked functional fits Non-destructive X-ray Fluorescence (XRF) thickness analysis; cross-hatch tape adhesion testing per ASTM D3359; micrometer measurement Coating thickness within the drawing-specified range, for example 5–12 μm where applicable; adhesion rating 4B/5B where required; masked zones free of coating buildup Vendor CoC, XRF thickness report, and hardness result when specified Thickness values below minimum blueprint limits; any coating delamination or peeling during tape testing; plating bleed over masked high-tolerance interfaces
Texturing / Polishing Cosmetic cavities, visual inserts, clear-view lens molding blocks Surface Finish Texture grade, gloss level, and draft condition on cavity side walls Optical gloss meter measurement; comparative inspection vs approved references under controlled lighting. Verify through mold surface treatment and finish control protocols Match the approved Mold-Tech, VDI, or polish reference; gloss within the specified range where applicable; no unacceptable rounding on protected parting lines or shut-off edges Texture reference coupon or approved sample, and gloss measurement record when required Mismatched texture pattern density or non-uniform orientation; gloss level drift on cosmetic faces; visible micro-erosion or drag marks on protected shut-off surfaces
Grinding / EDM Recovery Precision shut-off blocks, interlocking mold cores, micro-features, sub-inserts Mold Components Feature size, flatness, parallelism, surface roughness (Ra), and recast-layer condition after grinding or EDM recovery Digital micrometers, dial indicator tracking over surface plates, profilometer stylus analysis. Monitored for critical mold components affected by grinding and recovery work Size, flatness, and parallelism within drawing requirements; surface roughness (Ra) per drawing or process specification; no unacceptable recast layer or surface damage where EDM recovery is involved CMM report, surface roughness report, and demagnetization result when required Dimensions out of print tolerance; parallelism error exceeding specified limits; surface roughness values above limit; micro-cracking from thermal stress during heavy grinding

This matrix helps ensure that outsourced parts are verified against the required engineering and quality criteria before they return to assembly. These process-specific checks support the tool acceptance criteria before mold approval used before mold approval and assembly release.

Returned Documents Required Before Receiving Can Close the Lot

A returned lot is not considered complete until the required records match the exact part number, drawing revision, lot code, outsourced process, and acceptance criteria listed on the form.

Returned supplier documents checked before lot closure for outsourced tooling parts
Figure 4.1: Example of a returned supplier document pack including CoC, process log, verification report, and approved deviation record.

Receiving inspection of physical geometry alone is not enough to close the lot. If the supplier does not return the records required by the form, the lot should be placed on hold until document verification is complete. Depending on the process, lot closure may require a CoC, furnace record, hardness report, thickness report, CMM report, gloss or reference approval, and any approved deviation record.

CoC and Part/Revision Matching

Generic or non-part-specific Certificates of Conformance should not be accepted for outsourced tooling work. Each returned document should clearly identify the part number, drawing revision, and internal job or lot tracking code. Any mismatch in part number, drawing revision, lot code, or outsourced process should place the lot on hold until the record is corrected and reverified.

Process Logs and Process Certificates

Many outsourced special processes depend on heat-treatment cycles, plating conditions, or other logged process data that cannot be confirmed by visual inspection alone. For heat treatment, the supplier should return a furnace record that shows the actual process cycle for the lot. For plating or coating, the batch should be returned with the required process log or thickness report that matches the specified requirement. Heat treatment should return furnace and hardness records; plating should return thickness or process records; recovery grinding should return dimensional or roughness reports where specified.

Verification Reports Linked to CTQ

A simple pass/fail mark is not enough for CTQ features. The supplier should record and submit measured results for the CTQ features listed on the release form. CTQ verification may include size, hardness, coating thickness, surface finish, shut-off condition, or fit-critical features listed on the release form. These measured results should be filed with the project quality records to support tooling traceability through trial, approval, and maintenance, updating the corporate archive for returned quality documents and verification records.

Deviation / Rework Records

Unlogged adjustments at a supplier’s facility are a common cause of stack-up errors during mold assembly and fitting. If the supplier finds an out-of-tolerance condition or performs an unplanned recovery step, a deviation record should be approved and attached to the returned document package. This record must map directly back to our active engineering change and deviation control workflow before any concession or material release can occur.

Hold / Accept / Reject Logic at Receiving Inspection

Receiving inspection logic for outsourced tooling parts with hold review accept flow
Figure 5.1: Receiving flow showing document check, CTQ verification, hold/review decision, and final lot disposition.

Receiving decisions should not rely on visual judgment alone or unclear sign-off rules. Each returned lot should pass a defined hold, review, or accept gate based on part and revision match, required records, and receiving inspection results. At minimum, receiving should verify the part number, drawing revision, lot code, required returned records, CTQ check results, and any approved deviation record before closing the lot.

What Triggers Hold

Place the lot on hold immediately if the part number, drawing revision, lot code, or required records cannot be verified. Missing process records, incomplete hardness reports, quantity mismatch, or traceability issues should trigger a hold at receiving. Common hold triggers include part or revision mismatch, missing records, quantity mismatch, traceability loss, unresolved visual damage, or unverified CTQ results. Affected lots should remain in MRB or quarantine hold until the required records and disposition are complete.

What Can Be Accepted Directly

A returned lot can be accepted directly only when the required records are complete and the defined receiving checks are fully closed. This requires an exact match between the release form and the returned shipment records, along with acceptable CTQ results and no unresolved visual or handling damage. Direct accept is appropriate only when the returned record pack is complete, CTQ checks are within requirement, and no unresolved deviation or damage is present.

What Requires MRB or Engineering Review

Minor deviations that do not require immediate scrap should be routed to engineering review. Quality engineers and tooling engineers should review fit, function, and assembly impact before issuing a disposition through the mold validation and disposition workflow. Engineering review is required for minor dimensional deviation, cosmetic variance on protected surfaces, approved concession use, or any condition that may affect fit, shut-off, or downstream assembly.

Receiving Disposition Matrix

Risk Signal (Incoming Discrepancy) Immediate Action Release Condition (Gate Requirements)
Missing metallurgical data or unverified process records (e.g., hardness chart). Hold & Quarantine Release to production occurs only after the vendor report matches the part number, lot code, and drawing revision listed on the form.
Physical item quantity mismatch or untraceable batch lot codes. Hold & Quarantine Physical material hold is cleared after complete piece-count reconciliation, verified vendor correction, and formal QC manager closure.
Unclear cosmetic standard conformity or localized texturing variance on visual surfaces. Engineering Review Isolate in MRB area; component release requires an approved physical boundary sample or technical reference being appended to the tracking pack.
Minor, fully documented process deviation accompanied by prior vendor concession notes. Conditional Accept Route batch through standardized static inspection before assembly release; document compliance per approved MRB engineering disposition notes.

Common Failure Modes in Outside Processing

Outside processing failures usually come from wrong revision control, missing records, lot mix-up, dimensional shift, or undocumented rework. The sections below explain what usually goes wrong during outside processing, why it gets missed, what records the supplier must provide, and what receiving should verify before release. These failure modes are controlled by revision match, required returned records, lot traceability, post-process dimensional verification, and documented deviation approval.

Wrong Revision Processed

What usually goes wrong Suppliers may process or machine the part using an outdated drawing or CAD file when mid-job engineering changes are not communicated clearly.
Why purchasing misses it Purchasing may verify price, quantity, and due date on the PO, but not whether the supplier is working to the current drawing revision and release form.
What this form forces the supplier to provide A signed acknowledgment that the supplier has received and confirmed the current drawing revision, process requirement, and release form before processing starts.
What receiving must verify before release Receiving should verify that the returned part, drawing revision, and supplier records all match the current release before the component moves to the next tooling step, running direct audits via active revision control standards for outsourced mold work.

Missing or Incomplete Records

What usually goes wrong Suppliers may return generic CoCs that do not include the process-specific verification data needed for lot closure.
Why purchasing misses it Purchasing may treat a generic CoC as complete documentation, even though the required measurement records or process logs are missing.
What this form forces the supplier to provide The supplier must return the required reports or process records, such as furnace records, hardness reports, thickness reports, or other specified verification documents.
What receiving must verify before release Receiving should verify line by line that each required field on the release form has a matching returned record before the lot is closed. Required records may include furnace data for heat treatment, thickness reports for plating, gloss or reference approval for texturing, and CMM or roughness reports for recovery work.

Mixed Lots and Traceability Loss

What usually goes wrong High-similarity inserts or multi-cavity parts are treated together in bulk runs by the subcontractor, mixing separate material batches and scrambling tracking histories.
Why purchasing misses it Receiving or warehouse staff may verify the total quantity on arrival without checking the batch code, cavity ID, or part-level traceability marks.
What this form forces the supplier to provide Separate packaging and traceability labels for each lot, linked back to the original material heat lot or internal batch record.
What receiving must verify before release Receiving should verify cavity ID, part marking, or lot traceability marks on each component before release. If cavity ID, lot code, or part-level traceability cannot be confirmed, the lot should remain on hold to protect lot traceability and cavity-level tracking thresholds.

Post-Process Dimensional Shift

What usually goes wrong Heat treatment stress or coating buildup can change CTQ dimensions, shut-off fit, and other interface-critical features.
Why purchasing misses it Basic inspection may catch overall size but miss flatness, parallelism, or fit-related dimensional shift after processing.
What this form forces the supplier to provide Pre- and post-process dimensional data for the CTQ features listed on the drawing or approved inspection datum, focusing on fit-critical dimensions, shut-off surfaces, flatness, and parallelism.
What receiving must verify before release Receiving should perform a direct dimensional check of fit-critical features against the defined post-process tolerance requirements before release, in strict accordance with tolerance standards for post-process verification.

Undocumented Rework

What usually goes wrong Suppliers may perform unlogged recovery work, such as hand-stoning, re-polishing, or an additional heat cycle, after a process issue occurs.
Why purchasing misses it The part may still look acceptable in a basic visual check while hidden changes to hardness, fit, or surface condition remain undocumented.
What this form forces the supplier to provide The form should require the supplier to report any deviation or rework step and submit an approved deviation record before release.
What receiving must verify before release Receiving should review the process log, deviation record, and affected CTQ features before the part is released back to tooling. Any rework or process deviation should remain on hold until the deviation record is approved and the affected CTQ features are reverified.

Tooling Example: How We Verify Mold Components After Outside Processing

US engineering teams expect tooling components returned from outside processing to be supported by clear validation records before release to assembly. The mini-cases below show how returned records, CTQ checks, and release criteria are used to verify outsourced tooling components before they move to inventory or assembly. Each mini-case below shows the returned records, CTQ checks, and release conditions used to verify outsourced mold components before they return to tooling or assembly.

When H13 or S136 inserts are heat treated by an outside supplier, variation in the process cycle can affect hardness, dimensional movement, or cracking risk. Our release form identifies the CTQ dimensions and returned records that must be checked before the insert can be released back to tooling. If the supplier over-etches or over-polishes the surface, draft condition, shut-off edges, or cosmetic areas may be affected, leading to drag marks, scuffing, or ejection problems in molding.

Cavity core texture acceptance reference under controlled lighting comparison
Figure 6.2: Example of a texture or polish acceptance reference used to compare cavity surfaces under controlled lighting.

Sliders, lifters, cam tracks, guide surfaces, and core pins often depend on nitriding or coating for wear resistance and stable sliding contact. Incorrect coating thickness or poor surface preparation can cause delamination, galling, premature wear, or mechanism sticking during production. To counter these vulnerabilities, dedicated documentation verification rules separate initial sub-contracting logistics from active assembly tasks.

The final verification milestone occurs at the reassembly gate before the mold build continues. No assembly release should occur until the returned records and inspection checks are closed for the outsourced component, keeping unverified dimensional stacking out of your program. Clear signature protocols eliminate tracing data gaps across execution boundaries.

Core Insert After Heat Treatment

  • Target Hardness Range: Verified against drawing requirement or approved heat-treatment specification (e.g., 48–52 HRC where specified).
  • CTQ Seating Dimension Recheck: CMM check of fit-critical pockets or seating features to confirm post-heat movement stays within drawing requirements or approved grinding allowance.
  • Dimensional Movement Check: Comparison of pre-process and returned dimensional data for the defined CTQ features.
  • Required Returned Records: Furnace records, hardness reports, and batch traceability records linked to the selected mold steel selection for outsourced heat treatment risk requirement.

Cavity Surface After Texturing

  • Texture Standard Reference: Texture or polish acceptance should be based on an approved plaque, sample, or visual reference linked to the drawing requirement.
  • Protected Area Masking: Inspection of protected parting boundaries to confirm no visible acid bleed, over-etching, or unacceptable surface damage.
  • Visual / Light Condition: Visual evaluation under controlled 5000K lighting to check texture consistency, gloss condition, and visible surface defects.
  • Photo Retain Sample: High-resolution digital reference images logged under active protocols for surface treatment and polishing control for cavities and cores.

Slider/Lifter After Nitriding

  • Wear Surface Requirement: Deposition thickness and nitriding parameters calibrated to functional mechanism layouts.
  • Fit / Sliding Contact Check: Fit and contact checks against the mating surface or approved wear-contact requirement before the component is released to reassembly.
  • Coating Verification: Non-destructive thickness profile tracking checks conducted over dynamic sliding parameters.
  • Required Returned Records: Thickness data, hardness result, process log, and fit-check evidence for the sliding or wear surface across all wear components in injection molds.

Pre-Assembly Verification Points

  • No Assembly Release: Components should not be released to assembly if the tracking form is still open or the inspection status is incomplete.
  • Sign-Off Criteria: Release should be signed by incoming quality and tooling engineering when CTQ or fit-critical features are affected.
  • Traceability Archive: The completed outside processing record should be retained in the tool history file as part of the pre-assembly checklist after outsourced processing.

Professional Tooling Form Preview (PDF)

This PDF is a working record used to document part release, supplier return records, incoming QC checks, NCR or rework status, and final sign-off for outsourced tooling work.

What the PDF Covers Section by Section

The form is divided into five sections so buyers, SQEs, and tooling teams can track the part from outside release to receiving verification and final disposition. Each section records a different control point, which helps prevent missing documents and makes it easier to verify the returned lot against the standard incoming QC checklist for mold-related outsourced work.

Form Section Technical Parameters Logged & Controlled
1. Master Routing Information Release routing, part number and revision, supplier name, PO or job reference, and outsourced process type.
2. Part-Level Sub-Contract List Part tracking number, cavity or insert ID, lot quantity, and material or heat-lot reference.
3. Incoming Acceptance Record Measurement results, hardness results, coating or surface checks, and receiving verification entries.
4. NCR / Rework Log NCR details, rework action taken, deviation status, and approved engineering deviation record. Linked directly to our internal rework and change control in mold programs infrastructure.
5. Final Release & Sign-Off Final release sign-off, date fields, and final acceptance or hold status before tool-room release.

Best Way to Use the PDF Workflow

This PDF works best as a physical control record for supplier return review, department sign-off, and archived project documentation. Use the form at three points: before the part is sent out, when the supplier returns the lot with records, and when receiving closes or holds the lot. Even if the project is tracked digitally, this PDF gives the team a physical record that can travel with the parts and be reviewed again at receiving.

What Buyers Should Demand with Form Return

Procurement teams should require suppliers to return the specified technical records together with this form. Heat treatment should return furnace and hardness records; plating should return thickness or process records; recovery grinding should return dimensional or roughness reports where specified. A complete supplier verification package must contain:

  • Process Logs: Furnace records, plating process logs, or other process records required by the outsourced operation.
  • Inspection Reports: Thickness reports, roughness reports, CMM reports, hardness reports, or other verification results required by the form.
  • Traceability Documents: Supplier CoCs and lot records that clearly match the part number, revision, and internal lot ID on the form.

FAQ

Can this form replace PPAP or a control plan?

No. This form is only used for outside processing release, returned records, and receiving verification. It does not replace PFMEA, a control plan, or formal PPAP requirements for production approval for controlled production programs.

Can one form cover multiple parts and processes?

One form can cover multiple parts only if they share the same lot, the same drawing revision, the same outsourced process, and the same returned-document requirements. If different parts require different outsourced processes, CTQ checks, or returned records, use separate forms.

What should purchasing verify before approving outside processing?

Before approving outside processing, purchasing should verify the current drawing revision, the required process, any masking or protected areas, required returned records, and the internal approval owner before release. Purchasing should use a what purchasing should prepare before supplier release checklist to confirm the required process and records before dispatch.
